914 Wizard? No way. I got too much to learn.  Group: Members Posts: 4,099 Joined: 21-April 03 From: Gig Harbor, WA Member No.: 598  |
I run an MSD 6A ignition and I have been using Bosch W5CC plugs with a .050 gap. This time I couldn't find that plug so we substituted an NGK R5671A-7 with the same gap. I ran it for about 20 miles and the car runs great. Cylinder head temperatures are the same but when I checked the plugs they sure are lighter in color than I am used to. How long does it take to get an idea of the way the spark plug burns? Do I need more miles or is this plug hotter?
Thanks for your help, Dave |
